| Abstract | In order to preliminary investigate effect of HDS (Highly Ductile Steel) on the crashworthiness of struck ship, a series of large scale 3-dimensional ship-ship collision analysis are carried out using the non-linear finite element code LS-DYNA. A very large crude oil carrier (VLCC) is assumed to collide with midship region of another double hull (D/H) VLCC in right angle (90 deg.). Two collision points for the struck VLCC are assumed. One is between Swash Bulkhead (S.BHD) and Oil Tight Bulkhead (OT.BHD), the other is just on S.BHD. Damage extent and total absorbed energy until oil cargo tank ruptures in the case of HDS are compared with those in the case of conventional material. Critical colliding speed (VB,cr) is also compared. Effects of HDS on absorbed energy and VB,cr are discussed in detail. It can be found energy absorption by inner shell (IS) rupture with using HDS is about 2–3 times larger than that with using conventional It is also estimated that IS rupture does not take place when a striking ship collides in less than 8kt in the case of using HDS although a critical striking velocity in the case of conventional bow is about 4–5kt. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
